MEANS FOR ANCHORING OR SECURING TANKS ON UNDER/FRAMES.

Application filed August 2, 192a. Serial no. 129,664.

To all whom it may concern: I

Be it known that we, FRANCIS BRADLEY.

of. Philadelphia, county of, Philadelphia,

State of Pennsylvania, and ALLEN E. Os- 5 TRANDER, of Bronxville, county ofWestchester, State of New York, citizens of the United States, have'invented a new and useful Improvement in Means for Anchoring 0r Securing Tanks on Underframes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

In the transportation of certain classes of liquids and gases in tanks on railway cars, itis of the utmost importance that the tanks be held against longitudinal, lateral and vertical displacement with relation to the car body and to each other.- The tanks used in this construction are about the length and about one-half the width of the car bodyor underframe. It is obvious that where a capacity isrequired that is in excess of that l to be obtained by two tanks, the preferred arrangement would be to place a third tank above and between the other tw but no satisfactory means has been devised to secure tanks to each other and to the under'frame in such relation and to" avoid danger of one or all of them becoming freed from their fastenings under the. great stresses and strains arising in transportation. By our invention, we provide a new means of supporting the tanks on the car body or underframe and holding them thereon with such security that all danger of longitudinal lateral and vertical displacements is-avoided.

A preferred embodiment of the invention is shown in the drawings, in which- 40 Fig. 1 is a side elevation of a car body with the tanks mounted thereon.

. Fig. 2 is a vertical sectional view through one of the car bolsters, the tanks andthe securing means between such bolster and the tanks.

Fig. 3 is a central longitudinal sectional view through one of the car bolsters, the tanks and the securing means.

Fig. 4 is a plan view of the cradle super- 59 posed on the regular car truck bolsters.

. Fig. 5 is a detail sectional view taken on line 5-5 Fig. 2. v

The car body may be of any usual construction, a a representing the two usu'al transversely extending bolsters, one at each end of the car body.

Directly above each car bolster a we mount a cradle 25. This cradle may be integral with the bolster a, but it is preferred to make it a separate member and rivet it to the regular body bolster, and also to the.floor of the car if it is considered advisable to use a floor. Each cradle comprises two saddle portions, each comprising an upstanding flange c and a rest d conforming to the curvature of, and affording a rest for, a ring h secured to the tank'e resting on such saddle, as hereinafter described.

Each tank e comprises an elongated cylindrical body with conical-shaped ends. On the body portions of the tanks, adjacent each conical end, are formed two annular spaced-apart shoulders f and g. The "shoulder' f, which adjoins the conical end of the tank, is of less height than the shoulder g. The shoulder f is, preferably, of the maximum height that will permit a ring 72. to be slipped over it while the ring is hot and be shrunk into the groove formed between the two shoulders.

The two lower tanks 6 are placed on'the cradle b insuch position that each'ring h rests on the rest (1, and against the flange c, of the cradle b. The ring it is secured to the cradle by rivets or bolts 2' extending through the ring and the flange c of the cradle.

A top supplemental cradle or saddle 70, made in two parts, is adapted to be supported by the two lower tanks 6 and to directly support the single upper tank e. The curvature of its lower face corresponds to the curvature of the rings on the two lower tanks and the curvature ofits upper face corresponds to the curvature of the onno the upper tank; and it is )rovided with flanges corresponding to the anges c of the lower cradle b, which flanges are adapted to be engaged by and riveted to the rings )3. of the several tanks.

.To comply with the requirements of the railway interchange rules, straps a extend around the tanks and are secured attheir 'ends to the car frame. Such straps, howthe tanks are supported in accordance with our invention. are quite superfluous.

It is possible to dispense with the. shoulders 7, because the ring k is shrunk on the tank; and if there were any tendency to longitudinal displacement, it would be prevented in one direction by the shoulder g at one end of the tank and in the other direction by the shoulder g at the other end of the. tank. The principal function of the shoulders f is to insure that the ring h will be properly seated against the shoulder '9;

By the foregoing construction, all strains and stresses tending to displace the tanks longitudinally or transversely or vertically,

or tending to twist the tanks, relative to the car frame, will be effectually resisted.

Having now fully described our,invention, what we claim and desireto protect by Letters Patent is 1. The combination with a car frame, of a tank, a circumferential shoulder on the tank, a ring shrunk onthe tank adjacent the shoulder, and means supported by the car frame and engaging said ring and supporting said tank.

2. The combination with a car frame, of a tank, a circumferential shoulder on the tank, a ring shrunk on the tank adjacent said shoulder, and an arcuate' cradle supported by said frame and engaging said ring and supporting said tank.

3.,The combination with a car frame and its bolster, of a tank, a circumferential shoulder on the tank, a ring shrunk on the tank adjacent said shoulder, a cradle mounted on said bolster and supporting said tank, and means securing said ring to the cradle.

' 4. The combination with a car frame, of a tank, a circumferential shoulder on the tank,

a ring shrunk on the tank adjacent said its bolster, of a tank, two spaced apart circumferential shoulders near the end of the tank, the outer shoulder being of less height than the inner sh ulder, a ring shrunk on the tank between sZidshoulders, and a cradle supportedby the frame and secured to said 'rlng and supporting the tank.

7. The combination with a car frame and its bolster, of a tank carried thereby, two spaced apart circumferential shoulders near t e end of the tank, theouter shoulder bemg of less height than the inner shohlder,

a ring shrunk on the tank between said shoulders, a cradle mounted on the car .bolster, and means securing the cradle tov said rm.

8? The combination with acar frame and its bolster. of a tank carried thereby, a circumferential shoulder on the tank, a ring shrunk on the tank adjacent saidshoulder, a tank cradle mounted on the car bolster and extending transversely of the car frame and conforming in curvature to the tank ring and affording a rest and a side abutment f r the ring, and means securing the tank ring to the tank cradle. i

9. The combination witha car frame and its bolster, of a tank carried thereby, two spaced apart circumferential shoulders near the end of the tank, the outer shoulder being of less height than the inner shoulder, a

ring shrunk on the tank between said shoulders, and an arcuate cradle mounted on the car bolster and extending transversely of the car frame and affording a rest and a side abutment for the ring.

10. The combination with a car frame and its bolsters, of arcuate cradles mounted on the respective car bolsters, twoftanks ex tending lengthwise of' the car frame, rings secured on each tank near the opposite ends thereof,'and tank-anchoring means on said cradles comprising ring-engaging side mem- .bers and ring-supp rting rests conforming to the curvatures of the rings on the corresponding ends of the two tanks.

11. The combinatlon wlth a car frame and its bolsters, of cradles mounted on the respec-' tive car bolsters, two tanks extending lengthwise of the car frame, circumferential shoulders near opposite ends ofeach tank, rings shrunk on the tanks adjacent said shoulders,

and tank-anchoring means on each cradle its bolsters, of three tanks extending lengthi wiseof the car'frame, rings secured on each "tank near opposite ends thereof, lower tank cradles mounted on the respective car bolsters, tank-anchoring means on each cradle, two of said tanks extending side by side and supported on said means, top supplemental cradles overlying the two last named tanks, means on-the lower faces of the supplemental cradles engaging therings of, and supported by, the two lower tanks, and means on the upper faces of the supplemental cradles engaging the rings on, and supporting, the third tank.

13. The combination with a carframe and its bolsters, of three tanks extending lengthwise of the car frame, circumferential shoulders near opposite ends of each tank, rings shrunk on the tanks adjacent said shoulders arcuate cradles mounted on the respective car bolsters and engaging the rings and suprings onthe third tank and supporting and anchoring it.

14. The combination with a car frame and its bolsters, of lower tank cradles mounted on the car holsters, a pair of tanks mounted on said tank cradles, upper oppositely curved cradles mounted on said pair of tanks, a

third tank mounted on the upper cradles,

rings securedto the several tanks, means on the lower and upper cradles engaging the peripheral and side faces of the rings ofthe two lower tanks, and means on the upper cradles engaging the peripheral and side faces of the rings of the upper tank.

In testimony of which invention, we have hereunto respectively set our hands at Philadelphia, Pa., this 30th day of July, 1924:, and at New York city, N. Y., this 25th day of July, 1924.
